While a lot of us like to fantasize about a sexy pool boy living just outside our home (we'd also like to see Ryan Atwood strut out), Jennifer Lopez found having a man in her pool house to be a total nightmare! That could've been due to the fact that he was an unwanted and uninvited guest!

Sorry, not guest — STALKER!

According to Southampton police, 49-year-old John M. Dubis was arrested on J.Lo's Hampton's property earlier this month after living in her pool house for SEVERAL DAYS!

He walked around the grounds of her estate freely and even posted pictures of himself on Facebook hanging out at Jenny's pad!

Luckily J. Lo wasn't home but her security team was and they STILL didn't notice this intruder!

Way to do your job, guys!

Even scarier, this isn't the first time he's caused trouble for Jen! She already had a protective order out against Dubis after he contacted her mother earlier this year!

Ah! Stay away, dude!

Dubis has been charged with burglary, stalking, and criminal contempt and will now undergo a courtordered mental evaluation.

she purchase the home (LLC) in the wrong part of town because she couldn't afford a home like other stars in town on the water front like Taylor Swift, her house is not located in the rich area of town its in the valley, that why it got broken into where a bunch of homeless drug addicts live, so much for the LLc purchase, if her LLc company goes bankrupt, she just let the property go???
